Chi Squared Probability Table. The chi square distribution table is a table that shows the critical values of the chi square distribution. Therefore the probability that a chi square random variable with 10 degrees of freedom is greater than 15 99 is 1 0 90 or 0 10.
To look up an area on the left subtract it from one and then look it up ie. To find probability for given degrees of freedom read across the below row until you find the next smallest number. The table tells us that the probability that a chi square random variable with 10 degrees of freedom is less than 15 99 is 0 90.
The alpha level for the test common choices are 0 01 0 05 and 0 10 the following image shows the first 20 rows of the chi square distribution table with the degrees of freedom along the left side of the table and the alpha levels along the top of the table.
Table layout the table below can help you find a p value the top row when you know the degrees of freedom df the left column and the chi square value the values in the table. Chi square probabilities the areas given across the top are the areas to the right of the critical value. Table layout the table below can help you find a p value the top row when you know the degrees of freedom df the left column and the chi square value the values in the table. The alpha level for the test common choices are 0 01 0 05 and 0 10 the following image shows the first 20 rows of the chi square distribution table with the degrees of freedom along the left side of the table and the alpha levels along the top of the table.
